The TPS voltage should be within .03 volts of voltage shown on the label. Example: Gauge block voltage reading, "B" to "C" = 3.70 Gauge block voltage reading, "A" to "C" = 5.01 Divide 5.01 into 3.70, equals .07 voltage ratio from label." Very confusing, if my scanner was working, I'd copy it for you but it's out of service.
Jul 31, 2012 · Hi Steve! I really have no idea what could be causing this problem since you have 122.5 volts AC on the primary of the transformer and 42 volts AC on the secondary. Sounds like the transformer is bad if you do not have it hooked up to any low voltage wires. I will wait for you to grant me access to your Google Drive video.
My MAF signal wire is not getting voltage 0-5 volts. I have good ground to MAF i have good 12 volts power source to MAF iv replaced the MAF just to see if it would change anything. i have traced every wire back to ECU, more than twenty times to check for...
Wiring Procedure. NOTE: The wire labeled "Vref" is the +5V voltage source for the MAP sensor and the TPS sensor. This has two sensor connections: OPTIN+ on pin 30 and OPTIN- on pin 31. It is designed for use with 5 to 12 Volt (nominal) square wave signal, such as those from a Hall or optical...
Wire the output of the analog temperature sensor to a U3-HV as shown. Read the voltage on the computer to know the current temperature. This particular sensor outputs 0.01 volts per °F, so 0.76V corresponds with 76°F. Hardware with Analog Inputs
P0122 FORD Meaning The throttle position sensor responds to the accelerator pedal movement.This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module ().
Jul 20, 2018 · Ezgo Marathon has 4 wires (2 pairs) coming from the potentiometer. 2 wires carry the throttle signal to the speed control. 2 wires go to the reverse micro switch on the Forward and Reverse switch. When the F&R selector is in reverse this switch closes connecting these 2 wires which signals the pot to reduce the throttle signal by 50% so it puts ...

They have a power supply (typically 5 volts), a ground, and a signal return wire. Inside the TPS is a mechanical arm that’s attached to the shaft that holds the throttle blade. As the throttle moves, the arm makes contact at various points on a resistor strip. The correlating voltage is then sent through the signal line to the Powertrain Control Module. Newer TPS use a non-contact method and Hall effect-type sensors.
1(A). Trigger wire at the stator -- A simple type of crankshaft position sensor. Sends a signal to the CDI to let it know when to energize the ignition coil. Troubleshooting: - Disconnect the Black/Red and Blue/Yellow wires where they plug into the main harness (and connect to the BLK/R & BLK/W wires).
Jul 03, 2010 · First, its typical closed-throttle voltage signal is .50 volt. At wide-open throttle, the signal usually ranges from 4.10 to 4.50 volts. If you discover that the TPS signal is abnormally high, don’t overlook a bad sensor ground. Traditionally, the sensor ground wire is either green/yellow or green/white. A good TPS ground typically measures a voltage drop of .050 volt (50 millivolts) or less.
Jul 25, 2006 · The magnitude of the output signal at terminal 32 from the throttle position sensor 10 varies in dependence upon the position of the wiper 20 relative to the strip 12. Furthermore, since the wiper 20 mechanically contacts the resistive strip 12, the throttle position sensor 10 exhibits a contact resistance between the wiper 20 and the resistive ...

If you have two wire CLT and IAT sensors, their grounds (and the TPS ground) should run back to the DB37's pin #19 to reduce the potential for noise in the sensor signals. Since the MegaSquirt® EGO input (pin #23 on the DB37 connector) will accept a 0 to 5 volt signal, no changes are needed to the...
• Reference Voltage for the sensor should range between 4.9 to 5.1 volts. • Check for proper ground at the three wire sensor, it should be under .050 volts. • Short the VREF to the signal wire, it should register the reference voltage at the scan tool. This checks the Voltage supply circuit and the PCM ability to read the signal.
TPS2 sensor voltage out of range low, normally set if the TPS2 signal has shorted to ground, circuit has opened or sensor has failed. TurnOnMil. Check throttle connector connection and TPS2 sensor for an open circuit or short to GND. SECM Pin B4 (signal) to ETC Pin 5 SECM Pin B1 (sensor GND) to ETC Pin 2.

You can test the circuit by disconnecting from tps, probing between vref. (org/wht wire) and sig rtn (blk/wht wire) at the connector key on-engine off (koeo) if you get a 4-5 volt signal than recheck your wiring The TPS gets a 5volt signal from the CPU pin 26 (org/wht wire). The EGR position sensor, MAP/BP sensor and TPS share this voltage.
